Neuromuscular blocking properties of some bistropinium esters.

The neuromuscular blocking, anti-acetylcholine and ganglion blocking properties of two series of bistropinium esters were examined. The neuromuscular blocking activities of the mandelic acid esters of NN'-polymethylenebis(tropinium halides) were found to depend upon the number of carbon atoms (n) in the linking chain. Potency was enhanced more than 50 times as n was increased from 2 to 7. Compounds in which n equalled 7, 8, 9, 10 and 12 differed little in activity, but were generally more potent than tubocurarine in cats and rabbits. A peak of ganglion blocking action was obtained at the pentamethylene member. Esterification enhanced the feeble neuromuscular blocking properties of NN'-decamethylenebis(tropinium halide), the mandelic acid ester being more effective than the tropic, benzoic or phenylacetic acid esters in cats and rabbits. When two benzoic or mandelic acid esters of tropine were linked through their nitrogen atoms by a phenylenedimethyl grouping (-CH(2).C(6)H(4).CH(2)-), meta substitution was more effective than was ortho or para in producing neuromuscular block. The effectiveness of esterifying acids in m-phenylenedimethyl derivatives decreased in the following order, phenylacetic> tropic or mandelic>benzoic>acetic and diphenylacetic.
